In the early 1970's, when you had to select the right voltage setting for your TV to get a decent picture, the picture on Mum's black & white TV used to momentarily vanish with a burst of noise every time she started her 1950's Singer. I wondered if it was radiated interference or interference transmitted via the ring main, and thought would be instructive to try running the sewing machine from the cooker point in the kitchen via an extension lead. It did indeed fix the problem. Mum then used the cooker point until we got a new colour TV that wasn't bothered by the Singer.
